Hi I am not sure what year George was born in. I am of the believe that he and my g,g,g grandfather are related. I am thinking that they both maybe sons of Thomas Briggs.
Yes I have only come across the name of Mark Briggs once, the 1851 census as living with another family was a pauper, but no other info.
These are just some of the roadblocks I have encountered the 12 yrs or more researching my family. I have gotten as far as John. I believe that Thomas Briggs is either his father or grandfather.
